Procurement Notes
Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status directly with the supplier, as historical data indicates variations. Ensure the ordering suffix matches the required packaging format. Cross-reference the datasheet for any recent parameter updates or manufacturing changes.
Selection Notes
Select this component for applications requiring moderate inductance values in compact SMD footprints. Consider the 195 mA current limit when designing power-sensitive RF stages. The unshielded nature requires careful layout to minimize electromagnetic interference with adjacent components. Verify that the 2.5 Ω DC resistance aligns with system loss requirements.
Part Context
This part belongs to the 103R series of fixed RF inductors manufactured by Delevan. The series offers various inductance values tailored for radio frequency environments. The 103R-822KS specifically addresses needs for higher inductance within the standard 1008 package size constraints common in this product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official cross-reference guides or contact the manufacturer for validated alternatives.
